Explanation

Fitting and using the rear fog light are compulsory. It must only be on when weather or environmental conditions are especially bad, such as dense fog, very heavy rain, heavy snowfall or thick clouds of dust or smoke. It is used together with the sidelights and also with dipped headlights, main beam or the front fog light. The rear fog light can be switched off independently of the other lights.
